Abstract

A switch arrangement includes a switch component (20) and a bearing component (21). The switch component (20) is pivotally journalled with a pivot bearing (36) on the bearing component (21). The switch arrangement includes a switch (14) which has a contact spring (19). In an unactuated, closed position (47), the contact spring (19) lies against a contact (18) of the switch (14). A simple configuration of the switch arrangement and a self cleaning effect can be achieved when the pivot bearing (36) has a torsion section (35) which permits an overpushing of the switch (14) beyond the unactuated, closed position (47) into an actuated, closed position (37). The contact spring (19) then slides on the contact (18) between the unactuated closed position (47) and the actuated closed position (37) and cleans the contact thereby.
